Unlike filling the through holes with conductive or non-conductive materials first, the through holes are completely sealed with copper. However, due to the difficulty and high cost of production, this through-hole plug is no longer commonly used.
Excellent heat dissipation or transfer performance
Due to higher thermal conductivity and stronger current carrying capacity
100% prevention of solder leakage and dust/liquid entering through holes in SMT process
Very good stability and reliability
High cost
Imitation of via size and copper thickness
Low demand
Cover the via with LPI solder mask
Seal the through-hole with a solder mask layer
Non-conductive through-hole plug
